edit: i figured that my post is a bit besides the point of stamina in combat ... i leave it here anyways to annoy people ... hf For me, the poll is void.
First of, it all depends on the : How stamina is incorporated into the game; not the : IF.
The stamina shouldnt be visible like the stamina bar in the dev HUD in the vid. But i am pretty certain to recall that thats whats being aimed for - the immersive HUD - in the end. Like no floating banners and no HP bar and also stamina bar ... if possible. This requires good ideas as on how to implement indicators or cues for body states in different ways - like changed movement or breath sounds or flashing screen or color changes (like in CoD on low life) - and those are yet to be found, tested and implemented.
Secondly, stamina might be the best/optimal or even only possible design decision in order to overcome certain gameplay problems ... like the mentioned kiting problem. And as long as you dont find a better solution, its propably a good choice.
I for one would love to see an pro animator animate character states (stamina/arousal/exhaustion) how the char is feeling ... plus breath sounds+frequency+amplitude or coughing and face color and sweating indication ... a character footwork migh look sloppy or clunky/out of balance on low stamina.
This would cater most to the immersion as its utilizing empathy/mirror neuron system, which is propably the most immersive way you can have.
This is very hard to pull off and perhaps to expensive ... and it has potential to interfere with alot other things ... fighting moves/timings and stances would have to have states aswell (not efficiency wise, but indication wise).
Thats why it has to be done way, way down the road and needs placeholders like HUD bars for the time being ... perhaps as the very last thing to do, if at all.
I dont believe we will get this "immersive stamina HUD" - but i just wanted to show that it depends on the HOW not the IF something is done
